Taw qhia
1,2-Methylenedioxybenzene, tseem hu ua chunlanin, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm 1,2-methylenedioxybenzene:
Zoo:
1,2-Methylenedioxybenzene yog cov kua tsis muaj xim uas muaj ntxhiab tsw. Nws yog soluble hauv feem ntau cov kuab tshuaj organic, xws li cawv thiab ethers.
Siv:
1,2-Methylenedioxybenzene muaj ntau yam kev siv. Nws tseem tuaj yeem siv rau hauv kev npaj cov dyes, rubbers, thiab polymers.
Txoj kev:
1,2-Methylenedioxybenzene tuaj yeem npaj los ntawm reacting benzaldehyde nrog hydrogen peroxide. Cov tshuaj tiv thaiv tuaj yeem tswj tau los ntawm catalysts, xws li ferric (III) bromide, thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb:
1,2-Methylenedioxybenzene yog khaus thiab qhov muag inducing. Cov tsom iav thiab hnab looj tes tiv thaiv yuav tsum hnav thaum ua haujlwm. Thaum siv lossis tuav cov tshuaj no, tsis txhob nqus cov pa los yog nkag mus rau ntawm daim tawv nqaij. 1,2-Methylenedioxybenzene kuj yog cov kua ua kua thiab yuav tsum tau zam los ntawm cov nplaim taws thiab qhov kub thiab txias. Thaum khaws cia thiab siv, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo saib xyuas cov kev ceev faj tiv thaiv cov tsub zuj zuj ntawm ignition thiab hluav taws xob zoo li qub.
